Synthesis of a highly strained permethylenated cycloocta-1,5-diyne derivative by acid-catalysed thermal rearrangement

Abstract

Preparation of a dimeric derivative of 1,1,2,2-tetraethynylethane (3,4-diethynylhexa-1,5-diyne) and its unexpected rearrangement to a permethylenated cycloocta-1,5-diyne, the structure of which was confirmed by X-ray crystallography, is reported.
